August 2011

21 Which sediment is most easily picked up and transported by the wind?

(1) cobbles (2) pebbles (3) sand (4) silt

(3) low elevation with distorted bedrock

(4) low elevation with nearly horizontal layers of bedrock

28 Which two locations are found in the same major geographic landscape province?

(2) Elmira and Riverhead (4) Massena and Mount Marcy

30 The map below shows a meandering stream as it enters a lake. The arrow shows the direction of stream flow. Points A through D represent locations on the surface of the stream.

32 The diagram below shows columns A, B, C, and D that contain different sediments.

Equal volumes of water were poured through each column. Which column of sediment retained the most

water?

(1) A (2) B (3) C (4) D

Base your answers to questions 83 through 85 on the cross section below, which represents a glacier

moving down a mountain valley. The water from the melting glacier is flowing into a lake. Letter A represents

a location on the bottom of the lake.

83 Describe the most likely shape of a cross section of the glacial valley as viewed from the lake. [1]

84 After the glacier melts, what evidence might be found on the surface of the bedrock indicating that the

glacier had passed over the surface? [1]

85 Sediments found at location A range in diameter from 0.0004 to 0.006 centimeter. What name is given to

this size sediment? [1]

18 The cross section below shows the general bedrock structure of an area containing three different landscape regions, A, B, and C.

Which list correctly identifies the type of landscapes represented by letters A, B, and C?

(1) A = plain, B = plateau, C = mountain (3) A = mountain, B = plain, C = plateau

(2) A = mountain, B = plateau, C = plain (4) A = plateau, B = plain, C = mountain

21 The map below shows an overhead view of sediments that have accumulated at the bottom of a lake. Points A through D represent locations on the shoreline of the lake.

28 A stream’s velocity decreases from 100 cm/s to 5 cm/s. Which size sediment particles will still be

transported by the stream?

(1) pebbles, sand, silt, and clay (2) sand, silt, and clay, only (3) silt and clay, only (4) clay, only

34 The block diagram below shows a portion of Earth’s crust.

Which stream drainage pattern is most likely present on this crustal surface?

Base your answers to questions 44 through 46 on the map below, which shows a portion of the continent of

North America and outlines the Mississippi River watershed. Points A, B, C, D, and E represent locations on

Earth’s surface.

44 At which location would the Mississippi River’s discharge most likely be the greatest?

(1) A (2) B (3) C (4) D

45 Sediments deposited by the river at location B are best described as

(1) sorted and layered (3) unsorted and layered

(2) sorted and not layered (4) unsorted and not layered

46 Which landform is produced at location E where the Mississippi River enters the

Gulf of Mexico?

(1) a delta (2) a drumlin (3) an escarpment (4) an outwash plain

Base your answers to questions 51 and 52 on the block diagram and information below. The diagram is of

the Niagara Falls region as viewed from the north.

The Niagara River began to flow over the Niagara Escarpment about 12,000 years ago when the last Pleistocene ice sheet melted and retreated north from the Niagara Escarpment. Since that time, Niagara Falls has eroded upriver, leaving a deep, steepsided valley that is 11,000 meters long. The top bedrock layer of the escarpment is the Lockport dolostone which lies above the Rochester shale. The shale is more easily weathered than the dolostone. This causes the dolostone to be undercut. As a result, the dolostone breaks off in large blocks that tumble to the base of Niagara Falls.

51 In which New York State landscape region is Niagara Falls located? [1]

52 Toward which compass direction is the location of Niagara Falls likely to move in the future? [1]

(2) saturated and the slope is gentle (4) unsaturated and the slope is gentle

12 Which landscape surface resulted primarily from erosion by glaciers?

13 The formation of soil is primarily the result of

(1) stream erosion and mass movement (3) precipitation and wind erosion

(2) stream deposition and runoff (4) weathering and biological activity

14 Sediments found in glacial moraines are best described as

(1) sorted and layered (3) unsorted and layered

(2) sorted and not layered (4) unsorted and not layered

30 The block diagram below shows a cross section of a landscape. Letters A, B, C, D, and E represent

different rock layers.

Which rock layers appear to be most resistant to weathering?

(1) A and B (2) B and D (3) C, D, and E (4) A, C, and E

46 The diagram below shows an experimental setup to compare water retention and permeability in two columns with equal volumes of spherical plastic beads of different diameters.
